The theory of optical manipulation is not limited to spherical particles but tremendous efforts have been made to calculate the radiation pressure on various kinds of objects, such as, composite spheres [1]}, [2]}, spheroidal particles [3]}, nanorices [4]}, cylindrical particles [5]}, chiral spheres [6]}, [7]}, [8]}, [9]}, chiral nanocrystals [6]} and dielectric slabs [11]}, [12]}, [13]}, wherein the magnitude as well as direction of the optical  forces and the flow of optical momenta have been discussed.
Nowadays, metamaterials and metasurfaces are emerging fields that have potential applications in the field of nanotechnology, sensing and medicine [14]}. The negative radiation pressure on such surfaces, for instance, cell membranes, and chiral metasurfaces [15]} could be used to probe the local properties by stretching and relaxing the surfaces due to the incident light. To the best of our knowledge, the local radiation pressure on such metasurfaces has not been discussed so far.
